Painted into a corner, Need advice on how to do it Options

[worn]

Hi to all, especially you experts with a spray gun. I know who some of you are, and you know whom the other are.

I have now painted a few cars and since I stick to single stage and can color sand, it has worked out pretty well. Especially the easy parts.

What I haven't figured out is how to deal with inside corners. I understand that physics is against me, in that a ball or beam of light hitting a ninety degree inside corner wil come straight back at the sender. On inside corners, I sometimes cannot get coverage unless I settle for granular balls of paint that settle in the region. Tightening the pattern by closing the side jets that make the brush pattern for the gun seems to help as does using the smallest gun possible. I suspect though that expert advice would be better than my muddling through. Winter is closing in fast, so you have till spring to answer. Still, realistically you will have forgotten long before that, so please help me now instead.
I am using bare metal, covered with DP50, followed by K36 sanded, followed by Deltron. It is Bahia red, so it looks pretty much like a major crime scene when the paint is flowing. Thanks folks!! You are amazing people.

Is this for interior painting? First thing that came to my mind is how the H do you paint the underneath and inside of the targa bar?

Some guys don't like them, but to me using a pressure pot is the only way to go. The freedom to spin the gun upside down makes painting areas like underneath the targa bar easy and allows you to concentrate on laying down a nice consistent coat.

As for the corners, you're working against the air pressure. Ultimately you want the lowest pressure possible to get a good spray pattern for the amount of paint you're trying to get out of the gun at any given moment. Let's say your hand movement is slow, then you probably don't want the feed of paint to be high, because you'll glob the paint on in thick coats. So you should concentrate on finding the amount of feed that gives you the thickness of coat you desire. Then adjust the spray pattern pressure to get the spray pattern correct. Most newbie painters err on the side of too much overall gun pressure. They then have the issue you're having (called blowback). You notice it when doing corners, but a pro notices that he's just blowing a lot of paint out of the gun, and that costs tons of money. Because if it's blowing all over the booth instead of what you're painting, then yourr wasting the paint (called transfer efficiency, or in real terms...how much of that gallon of paint I just sprayed ended up on the car versus on the floor, me, the walls and out the exhaust of the booth?). Good paint is too expensive to waste by sending it through an exhaust filter and up a stack and out into the atmosphere! Good luck!!!!!

Yeah. At around $500 for a gallon mixed it seems important. Yes it is the interior, but I also have a hard time getting the inside of lids painted because no matter how hard I try there is always some dust under the reinforcement web. Especially after I strip the paint off either by sanding or aircraft stripper. I know, more than one problem. The airflow tip is a great one.

So in some cases is an HVLP working against me? I thought they had higher transfer rates, but they also shoot a lot of air. Or maybe I try turning down the pressure. Thanks!
